Cassidian
and Astrium Services recently staged a live demonstration on how
satellite communications could connect Tetrapol regional networks in
Brazil. The two companies created an end-to-end communications
solution to enhance Brazil's border surveillance capabilities and to
show the advantages in combining SATCOM and digital
radio
communications.
Cassidian's
Tetrapol professional
mobile radio (PMR) networks
provide secure radio communications to Brazil's Departamento de
Polícia Federal (federal police force) and other government offices.
Brazil operates nine Tetrapol regional wireless IP networks, which
provide wireless communications coverage from the Atlantic coast to
Brazil's borders with nine South American countries.
Terrestrial
infrastructure usually links up Tetrapol regional networks. However,
there are plenty of remote areas in Brazil that lack such
connections.
Astrium
Services provided its SKYWAN technology as a new way to connect
several networks. DAMA technology allows networks to share bandwidth
between all the nodes over satellite links.
The
satellite solution's scalability will expand Tetrapol's service
offerings, allowing them to be delivered through tactical temporary coverage
as well as permanent regional coverage. And it will not be limited to
Tetrapol's voice communication services.
The satellite link generated
by Astrium's SKYWAY and DAMA technologies will provide access to
Internet from satellite services and allow for numerous media
applications and data transmission services.
